Description
Application
It is usually connected with display meter, recording meter and computer, etc. to directly measure temperature of liquid, vapor, gas and solid surface ranging from -200 to 500 during various production process.
Features
With quick thermal response, reducing dynamic error
Small diameter, no limit on length
High measuring accuracy
Imported film resistor with high reliability and stability
Operation Theory
It is based on that temperature change of material results in change of its resistance. When resistance value changes, the working instrument will display relevant temperature.
